Westover et al. 95 prepared lightly crosslinked nitrated poly(4-hydroxystyrene) microspheres for pH sensors. The microspheres were produced using SPG membranes followed by suspension polymerization and they showed diameters between 1 and 2 micrometers. 

Infrared Spectra (IR) - Infrared spectra of cellulose nitrate, poly (methyl methacrylate) and cellulose nitrate-g-poly(methyl methacrylate) films were recorded using a Perkin-Elmer 337 grating IR spectrophotometer.

To a very limited extent, other polymers have been coacervated by this process to form microparticles, i.e., ethylcellulose, cellulose nitrate, poly(methyl methacrylate), cellulose acetate phthalate, poly(acrylonitrile-co-styrene), and poly(styrene). " For some of these, liquid poly(butadiene) (8-10 kDa) was employed as a coacervating agent. 

Nitration, like halogenations, occurs preferentially at the 4- or 5 position in A/ -unsubstituted and A/-substituted imidazoles. As with all nitrations, poly-nitration can occur, and there is the potential for subsequent thermal hazards or runaway reactions. Despite its lack of reactivity, polynitration products have been reported.

In the present study, spinel ferrites nanocrystals with different structures were prepared from an aqueous solution containing metal nitrates, poly (vinyl pyrrolidon), and deionized water using a relatively low temperature thermal treatment method, followed by grinding and calcinations. No other chemicals were added to the solution. This method is environmentally friendly in that it neither uses nor produces toxic substances, and it offers the advantages of simplicity, low cost, and low reaction temperatures. The textural and morphological characteristics of the spinel ferrites nanocrystals we prepared were studied with various techniques to determine the influence of calcination temperature on the crystallization, morphology, and particle size distribution of the nanocrystals and to explore other parameters of interest.
